Hi, so when i go on e621 i use blacklists to make sure i don't see women (am very gay) but today my blacklist didn't work, i blacklisted terms that that i didn't want to see and the posts were still there, please help.

make sure your blacklist is set up like this:
female
feces
gore
cub
vore
watersports

not like this:
female feces gore cub vore watersports

One word per line. Otherwise, it will only blacklist posts with all tags on it.
And make sure the post, you were mentioning, is properly tagged. If not, tag it by clicking on edit underneath it ^^

Here is the blacklist help page for more details.

Make sure the blacklist is enabled under the search bar.

I was worried for a moment... mine works just fine.
